No.  Never had anything like that happen, and I've been using Fedora as my primary OS since Core 3.

How
did you "install" Acrobat Reader?  Did you use yum and the Adobe repo? 
How did you download the other programs that you didn't install?  Yum? 
Or did you download the rpm's directly from a non-repo site?

Really,
since you just installed 12, save yourself a lot of time:  Do a clean
reinstall of 12 overwriting everything.  At the first boot, before
updating, disable selinux, then in the terminal of your choice: enter

  'su -'

give
the root password, and do your 'yum update'.  After completing, set up
the other repos that you want, and install your other apps.  The
following link will help a lot:

This can happen if you decide to take the bios properties and do what is called pushing to get the last bit of performance. During the boot process, memory timing fails, and the system crashes.  Set the bios parameters to default and restart your system.

How do I know. I was experimenting at trying to boost system performance, and had this happen to me.  I could only increase performance by about 5% safely.  Overclocking, and pushing memory access is a trial and error exercise. Best to go with system defaults.
